Montana Title 26. Evidence § 26-3-201. Effect of judgment or final order--when conclusive

(1) In case of a judgment or order against a specific thing, or in respect to the probate of a will or the administration of the estate of a decedent, or in respect to the personal, political, or legal condition or relation of a particular person, the judgment or order is conclusive upon the title to the thing, the will or administration, or the condition or relation of the person.

(2) In other cases, the judgment or order is, in respect to the matter directly adjudged, conclusive between the parties and their successors in interest by title subsequent to the commencement of the action or special proceeding, litigating for the same thing under the same title and in the same capacity, provided they have notice, actual or constructive, of the pendency of the action or proceeding.
